Abstract (en)
[origin: EP3611390A1] A tubular structure (100) is described herein comprising an elongate tubular member (10) extending between a first end (10a) and a second end (10b), wherein the tubular member (10) comprises an inwardly tapered portion (10c) adjacent said first end (10a), the inwardly tapered portion (10c) narrowing the tubular member (10) in a longitudinal direction towards said first end (10a). A nut (20) is also provided internally of said tubular member (10) at said inwardly tapered portion (10c), said nut (20) having an outer surface (21) that is in contact an inner surface (12) of said tubular member (10). An annular member (30) is also provided externally of said tubular member (20) at said inwardly tapered portion (10c), said annular member (30) having an inner surface (31) that is in contact with said outer surface (13) of said tapered portion (10c). The inner surface (12) of said tubular member (10) at said inwardly tapered portion (10c) is tapered so as to extend at an angle that compliments an angle of the outer surface of said nut (20). The outer surface (13) of said tubular member (10) is tapered so as to extend at an angle that compliments an angle of said inner surface (31) of said annular member (30). The structure also has at least one channel (150) that is provided so as to extend from said outer surface (32) of said annular member (30), through both of said annular member (30) and said tubular member (10) and also to extend at least partially into said nut (20). The structure further comprises a securing member provided within said channel (150) so as to extend from said external surface (32) of said annular member (30), through said tubular member (10) and at least partially into said nut (20).
